February 12 CW: continuation of similarity stations/group work
HW due Wednesday, 2/17:
Answer the following questions in complete sentences:
1. What do similarity and congruence have in common? What is different? Describe in general terms and with one example.
2. What is a scale factor? Describe in general terms and with one example.
3. When might you use a scale factor in real life?
4. What is a similarity statement? How does it allow the reader to identify corresponding parts of similar figures? Describe in general terms and with one example.
5. Similar figures with a scale factor of 1 are congruent. Explain, briefly.
Below the diagram on your homework, please replace the given directions with the following:
"In each part (a)-(d) below, some additional assumptions about the picture are given. In each problem, determine whether the given assumptions are enough to prove that the two triangles are similar; and if so, what the correct correspondence of vertices is (NOTE: this is related to the similarity statement... be sure that you are correctly identifying corresponding parts). If the two triangles must be similar, identify a theorem. If not, explain why not."
